Title: Improvements in wet and dry jigs for classifying particulate material such as, for example, coal and ores
IPC: B03B5/24
Filed: 1961-02-22
Abstract: 946,414. Radiation absorption control systems. MANNESMANN A.G. Feb. 22,1961 [Feb. 26,1960; Oct. 18,1960; Nov. 25, 1960], No. 6441/61. Heading G1A. [Also in Division B2] In a jig for separating materials of different densities, the composition of the material drawn off from the jigging bed is continuously controlled by a control system responsive to the absorption of radiation by a detector associated with a source in a zone of the jigging bed where stratification according to density is complete or nearly complete. In the diagrammatic arrangement, Fig. 1, the composite material 2 is fed over a screen 3 and agitated vertically by compressed air-blasts controlled by valves 4 so that separation by density takes place. A detector 5, which may be a counter, is located within the composite bed and is irradiated by a source of radiation, for example, an isotope of cobalt. The output from the detector 5 varies in accordance with the passage of the radiation through one or the other of the component layers, and may be utilized to control means for altering the rate of draw-off of, for example, the lower layer of the bed through controllable openings 9. A number of detectors 5 may be utilized at spaced positions in the direction of travel of the material, and two vertically spaced detectors may be employed at one or more of the positions, Figs. 3 to 5 (not shown). In a further arrangement, Figs. 6, 7 (not shown), the material on the bed is subjected to air blasts from a blower and is oscillated prior to its examination by a detector subjected to radiation from sources on each side of the bed, and in a modification, Figs. 8, 9 (not shown), or figs. 3, 4 (not shown), a measuring device is added to furnish a continuous indication of one of the components of the mixture. In a further modification, Fig. 10, to prevent loss or incorrect removal of the smaller particles, should the valve 9<SP>1</SP> be held open by a large lump such as that indicated at 16, when there is an excess of the less dense material and the valve 9<SP>1</SP> should be closed. The less dense material causes a signal from the detector 8, and if this signal persists for more than a predetermined interval, the switch 15 is operated to open the valve 9<SP>1</SP> for a short time to allow a large lump such as 16 to be released, if it is impeding the closing of the valve, and the valve to be reclosed after a short interval so that the less dense material is fed over its normal, i.e. upper, path for correct disposal.

Title: Improvements in discharge lamps employing luminescent material
IPC: H01J63/00
Filed: 1938-03-01
Abstract: 515,298. Discharge lamps. DEHN, F. B. (Heatless Light Corporation). March 1, 1938, No. 6488. [Class 39 (i)] A lighting source comprises a gas-filled envelope 6, Fig. 2, a luminescent surface 10, anode 8 and a cold cathode 7 having a large emissive surface so positioned and shaped, for example curved as shown, that its normal projection includes at least the luminescent surface. The luminescent material may be one or more of such substances as kunzites, calcites, sulphides of zinc, cadmium, barium, strontium and calcium, willemite, cadmium tungstate, calcium tungstate, uranyl salts, metallic salicylates, calcium arsenite &c., and is carried in a metal holder 17, which is mounted on an insulating support 25. The accumulation of electrical charges by the luminescent material is prevented by connecting the container 17 to earth or the anode circuit, and making the luminescent material conductive either by mixing it with a metal powder or embedding it in a metal mesh base. The luminescence is stated to be enhanced by heating, and a heating coil may be embedded in the support 25. An electrostatic grid 29 to which an alternating or direct potential is applied may be arranged in front of the surface 10 for the same purpose. External metal coatings 16a, with or without internal metal coatings 16b, are formed on the envelope and are at least co-extensive with internal extension of the electrodes, for the purpose of neutralizing stray electrostatic charges on the walls of the envelope. The electrodes are preferably made of materials such as sodium, potassium, barium, strontium, calcium magnesium or aluminium, either singly or in combination. The gas-filling may be residual air with the addition of argon, neon, and helium either singly or in combination, or hydrogen, nitrogen and carbon dioxide, alone or in combination. A working range of pressure for helium is given as between .1 to .01 mm. of mercury with potentials ranging from 1,000 to 25,000 volts. To correct the tendency of the tube to harden during use, a gas generating substance is contained in a porous thimble 12 housed in a side tube 15 and heated when required to liberate gas. A modification is shown in Fig. 4, in which the anode 44 is housed in a separate extension 41 connected to the main part 40 of the envelope by a neck 42 and hollow stem 45 with an aperture 46. The luminescent material is carried on both sides of a plate 49 held by screws in a metal sleeve 47 on the inner end of the stem 45. The cathode 51 is a circular or rectangular plate with a crease parallel to the plate 49. In a further modification, the cathode is in the form of a thick rod running axially of an elongated envelope. The luminescent material is applied to the wall of the envelope, and the anode is in a separate chamber communicating with the main part of the envelope through a small aperture. The device may be adapted for full or half-wave operation on ordinary commercial A.C. supply sources by including a transformer in the supply circuit.
